Pioneer speakers in Pakistan

Hi guys, I want to know where I can buy the Pioneer SP-PK21BS in Karachi. I have looked at two shops, Nashco and Desert Sound but they don't have it. Is there any Pioneer seller in Karachi? Please help me as I really want these speakers. http://www.pioneerelectronics.com/PUSA/Home/Home-Theater-Systems/Speaker-Packages/SP-PK21BS
